Application filed Ma 26, 1923. Serial No. 641,657.

separating process, and the rehandling of the water and wet ores as is now frequently necessary, the machine delivering the values ready for the smelter without further treatment, and further separating material ,with

,a very small difference of specific gravity between the same.

Another important object of the invention resides in the provision of a machine wherein a suction chamber isemployed and arranged within a rotatable drum, so that .the lighter material can be separated from the heavier material as the drum is rotated, means being provided foreifecting an adjustment of the suction chamber so that the latter will efficiently operate to draw particles varying in weight and size.

Other objects and advantages will appear when the following detail description is read in connection with the accompanying drawlng, the invention embodylng a structure which is dustless in operation, and one requiring a minimum of horse powerifor its operation, while the'general simplicity and durability of the machine constitutes other important features of the invention. In the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein:

' Referring to the drawing indetail' 10. in-

dicates a casing mounted upon a suitable base 11, it being understoodthat the casing can vary in size and configuration without departing from thespirit of the invention. This casing is provided with a door 12 by means of which access may be had to the casing when desired. Arranged upon the top of this casingis a drum 13 which is slightly tapered toward one end and has its interior surface roughened in any suitable manner to effectively agitate the material introduced into the drum while the latter is being rotated. The drum is supported by spaced pairs of rollers, the rollers of each pair being indicated at 10 and arrangedfadjacent the opposite ends of the drum. These rollers operate in the space between the annular flanges 11, there'being awpairjof these flanges for each pair of rollers as shown in Figure 1. .An internal feed. the material evenly while'thedrum is in operation, it being understood thatthe flange 1 L is'formed on the drum adjacent the; intake end thereof. and is utilized to drum. rotates very slowly. jThe material" to bedealtflwith is arranged within the hopper,15,-]the latter beingxequipped with a jvalv e 16 atjthe lower end thereof, and which valve controls the communication between ther hopper 15 and the supply tube ,17 which leads from the lower end of the hopper into one end of the drum 14. The material in this manner is conveyed to the drum, which is rotated as above stated, and it is duringthis'operation of the drum that heavier material and drawn intothe suction'chamber arranged withinthe drum 14.

the lighter material is separated from the g trough or the like "18 whichis mounted upon the top of the casing 10 and at an ,inclination 'to the latter, from which trough the said material is conveyed to :a suitable storage bin, or, in short,to its proper destination. It will be noted that when the material leaves'the supply 'tube 17 and enters the drum it contacts with an apron 19 which tends to spread the material as will be readily understood. i j a i The suction chamber above referred to includes a'flat top portion 20 and a curved corrugated and perforated bottom portion 21, the chamber is mounted upon an elbow 22 for partial rotation for a purpose to be,

presently described, it being noted that said elbow connects the said chamber with the suction pipe 23 which passes through the top of the casing 10 and mounted for slidable and vertical adjustment thereon. A set screw 24 is used to hold the suction chamber in a given position after it has been rotated upon the elbow to meet certain requirements, it being apparent that the curved bottom 21 of this chamber corresponds to the curvature of the drum 14 in which it is arranged. In addition to being susceptible of being rotated upon the elbow 22, it is also mounted to beadjusted horizontally along this elbow, the set screw 24: being used in this instance to hold the suctionchamber fixed with relation to the drum in a certain position. A lock nut 25 also holds the suction pipe 23 fixed with relation to the casing 10, notwithstanding thev fact that this pipe is also capable of being, adjusted vertically with a consequent adjustment of the suction chamber within the drum. This adjustment ofthe suction chamber is necessary to position it with relation to the drum in order to allow particles of different size and weight to be sucked into the chamber incident to the use of the machine. I The suction for the chamher. is created by a suction blower 26 having an air exhaust 27. The suction blower of course embodies a shaft 28 supporting a pulley 29 over which is trained a belt 30 so that the shaft and blower can be operated froni any suitable source of power located at a remote point. As the material is turned over and over within the drum l l as the latter rotates, the lighter particles are drawn into, the perforated suction chamber and conveyed into the casing A through the elbow 22 and the suction pipe 23, and this lighter material is deposited upon a bafiie plate 31 arranged within the casing 10 sort of diagonally to overlie the suction pipe 23. The casing is provided with an outlet opening normally closed by a cover 32. which may be of a resilient character or held in its normal position by suitable resilient means indicated at 33 and to which closure the lower end of the baffle 31 is connected. So. when the weight of the material deposited upoirthe baiile becomes great enough to overcome the resilient means 33, the cover 32, is opened to allow the escape of this material from the casing 10. The casing is also provided witha valve 3% which may be adjusted to regulate the force of suction or draft through the suction pipe 23 and the suction chamber. above described. Carriedby the suction chamber just mentioned is a dust shield 36 which is arranged in close proximity to the discharge end of the drum14.

While the drum may be rotated in any suitable manner, I preferably employ a bearings 37 as shown in Figure 1. The

lower end of-this shaft is provided with a bevelled gear 38 which meshes with a simi- I lar gear L0 carried by the adjacent end of the blower shaft 38. The upper end of this shaft 37 is provided with a worm. gear 39. The other worm gear 39 meshes with a ring gear 42 carried by the drum, so that the latter is rotated simultaneously with the operation of the suction blower. The machine is very simple in eonstruction and highly advantageous in operation for the purpose intended, and its use embodying all of the advantages herein above pointed out.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed. 7

Having thus described the invention, I claimi 1. An ore concentrating machine comprising a casing, adrum mounted for rotation thereon and adapted to receive the material to be dealt with, means for creating a suction in said casing, a perforated suction chamber horizontally disposed within the drum and communicating with said casing,
